The area surrounding Teide National Park experienced a fresh episode of seismic activity during the early hours of Monday, as the National Geographic Institute (IGN) detected more than 60 earthquakes beneath the Las Cañadas del Teide area in just a few hours.
These latest tremors add to the seismic swarm that began on Friday, bringing the total number of earthquakes recorded across Tenerife to more than 200 over the course of the weekend and into Monday morning.
According to the IGN, the overwhelming majority of these earthquakes have been of very low magnitude and are consistent with the normal seismic-volcanic activity expected on an active volcanic island such as Tenerife. The events have largely occurred beneath the central part of the island, particularly around the Teide National Park, where similar seismic episodes have been observed on previous occasions.
The most recent earthquake in the sequence was registered at 04:45:33 on Monday morning. It measured magnitude 1.0 and originated at a depth of approximately 19 kilometres, making it imperceptible to the vast majority of the population.
No Increase in Eruption Risk
Despite the noticeable increase in the number of recorded earthquakes over recent days, the National Geographic Institute has stressed that there is no indication of an increased volcanic hazard and that the current activity does not suggest a higher likelihood of an eruption in either the short or medium term.
Scientists explain that seismic swarms of this nature are relatively common in active volcanic systems. In Tenerife, low-magnitude earthquake sequences occur periodically as part of the island’s natural geological behaviour and, on their own, should not be interpreted as signs that volcanic activity is escalating towards an eruption.
Experts emphasise that volcanic unrest is assessed using a wide range of monitoring parameters rather than seismicity alone. Ground deformation, volcanic gas emissions, thermal anomalies and other geophysical indicators are continuously analysed before any changes in volcanic alert levels would be considered.
Continuous Monitoring Across Tenerife
The IGN continues to maintain round-the-clock surveillance of volcanic activity across Tenerife through a network of more than 100 monitoring stations distributed throughout the island. These stations continuously record seismic movements, ground deformation and other geophysical data, allowing specialists to identify even subtle changes in volcanic behaviour.
Every earthquake detected is carefully analysed by teams of seismologists, who assess both its characteristics and its relationship to the island’s broader volcanic system. So far, the information collected indicates that the current sequence remains within the range of activity previously documented in Tenerife.
A Weekend Marked by Seismic Activity
The weekend has been one of the most active periods of seismic monitoring around Las Cañadas del Teide in recent months, with hundreds of small earthquakes recorded beneath the island’s central volcanic complex. Although the number of events has increased, their magnitudes have remained low and their depths are consistent with previous seismic swarms observed in the area.
The IGN will continue to monitor developments closely and provide updates should any significant changes occur. At present, however, there are no signs that the current activity poses a danger to the population.
Authorities continue to encourage residents and visitors to rely exclusively on official information issued by scientific institutions and to avoid alarmist interpretations circulating on social media. Specialists reiterate that Tenerife is a volcanically active island and that episodes of low-level seismic activity form part of its normal geological evolution.
